Hello Eric,
This is an attempt at fixing support for negative X/Y positioning of
various FB formats. I kept you as the author since I started from your
initial work and fixed a few things + split the changes in several
commits. Let me know if that's a problem, and I change the author.
This series has been tested with a modified modetest (support for this
modifier has been added).
Note that I plan to test/debug support for negative X/Y positioning of
SANDXX planes.
Regards,
Boris
